Battery Tray

I have a 2006 Holiday Rambler, the other day I pulled the battery tray out to check the level of the fluids, whoever owned this unit before us put what appears to be baking soda in the trays to prevent corrosion I guess, I have heard of this working.
Anyway has anyone tried to use the spray0n rubber liner like for P/U Beds??
It claims to be acid resistant and would sure look better than a tray full of white powder.

your batteries really shouldn't be making a big mess. the factory magnum inverter charger is a 3 stage unit and it will do a good job of keeping the batteries charged without boiling them and dumping a lot of liquid or vapor...

every spring, I disconnect all the cables, remove the batteries, clean the battery tray and batteries with baking soda, make sure all the connections are cean and good, and put everything back together.

Checking water level in the batteries is done quarterly, and generally takes nearly a gallon of distilled water to top off all 4 U2200's.

What you suggest will certainly work. However, this shouldn't be a problem with a properly vented battery area and a multi-stage charger, which won't boil the batteries continuously. My 14 yo MH has never had a corrosion problem in the battery area.Although in recent years, I changed to a "smart" charger.

I've read in numerous posts about corrosions problems. I can only contribute this to poor ventilation by the mfg.

In this situation, adding mineral oil to the batteries can reduce out gassing which helps reduce corrosion.
